summ_prob_true: Summarize boolean distribution with probability

In pdqr: Work with Custom Distribution Functions

Summarize boolean distribution with probability

Description

Here summ_prob_false() returns a probability of 0 and summ_prob_true() - complementary probability (one minus summ_prob_false() output). Both of them check if their input is a boolean pdqr-function: type "discrete" with x in x_tbl identical to c(0, 1). If it is not, warning is thrown.

Usage

summ_prob_false(f)

summ_prob_true(f)

Arguments

f	A pdqr-function representing distribution.

Value

A single numeric value representing corresponding probability.

Other summary functions: summ_center(), summ_classmetric(), summ_distance(), summ_entropy(), summ_hdr(), summ_interval(), summ_moment(), summ_order(), summ_pval(), summ_quantile(), summ_roc(), summ_separation(), summ_spread()

Examples

d_unif <- as_d(dunif)
d_norm <- as_d(dnorm)
summ_prob_true(d_unif > d_norm)
summ_prob_false(2 * d_norm > d_unif)

# When input is "continuous" function or doesn't have 0 as distribution
# element, probability of being false is returned as 0.
summ_prob_false(d_unif)
summ_prob_true(new_d(2, "discrete"))
